Dunlop Geomax MX3S Rear Tire Review

The Dunlop Geomax MX3S rear tire features Progressive Cornering Block Technology (PCBT), an enhanced Carcass Tension Control System (CTCS), multiple block distribution, a controlled-rebound rubber element in the sidewall, and the elimination of the tie-bar design.

The Progressive Cornering Block Technology (PCBT) is Dunlop’s patented block-within-a-block design that offers more progressive cornering action and aids in slide control. The Carcass Tension Control System (CTCS) enables carcass flexibility from recesses, which are placed strategically along the tire carcass to aid in smoother ride characteristics and improve straight-line stability.

The multiple block distribution features varied pitches and angles of the tire blocks. As a result, fewer blocks are needed in the center area, which enhances contact feel. The controlled-rebound rubber element in the sidewall helps to damp out bounce and also acts as a suspension component within the tire, so the tire can better follow the track surface. Lastly, Dunlop opted to get rid of the tie-bar design in order to reduce the resistance toward bending within blocks. This enhances contact feel and performance in sandy and muddy conditions.

Despite being labeled a soft to intermediate terrain tire, the MX3S rear tire performs well in all conditions. It works exceptionally well in the terrain it is designed to, as I noticed an improvement in both high-speed stability as well as cornering in deep, loamy ruts. The cornering improvement is a result of the Progressive Cornering Block Technology, as the outer knobs are able to flex thanks to the additional knob within the main knob.

When used on hard pack terrain, the tire hooked up better than I anticipated. However, using the MX3S on harder terrain for extended periods of time makes the tire wear a bit faster than normal. With that being said, I was pleased with how the tire resisted wear during my time using it.

Seeing as it is a soft to intermediate terrain tire, I assumed the softer rubber would be more susceptible to wearing quickly when used in any dirt condition. However, this was not the case. The knobs maintained their sharp edge and height after several rides in a variety of different terrain from the soft and loamy to the hardest of dirt conditions.

With a retail price of $134.95 for a 100/90/19 size, the Dunlop Geomax MX3S rear is a bit pricier than other rear tires on the market. However, the increased traction available on all terrain types from soft to hard is ideal for anyone who is serious about riding and/or racing. Also, the fact that nearly every single professional rider uses the Dunlop MX3S rear is a testament to the tire’s performance as well. Overall, I am very pleased with the increased traction as well as the durability offered by the Dunlop MX3S on our 2016 Yamaha YZ250F.
